FOLDING CHAIR.

SPECIFICATION forming part of Letters Patent No. 484,058, dated October11, 1892.

Application filed June 24, 1890. flerial No. 356,555- (No model.)

To all whom it may concern.-

l 3e it known that I, DAVID A. SINSABAUGH, a citizen of the UnitedStates,residin g at Utica, 1n the county of Licking and State of Ohio,have invented new and useful Improvements in Folding Seats for Chairs;and I do hereby declare the following to be a full, clear, and exactdescription of said invention, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which form apart of this specification.

My invention relates to a novel construction of stop device for foldingseats of chairs, and more particularly for those used in operahouses,concert halls, and similar places; and my invention consists in a novelconstruction of stop-plates adapted to be secured to V the edge of thefolding seat, provided wit-h stop-faces on an incline corresponding tothe incline of the standards of the back and legs and arranged in suchmanner that the seat is engaged with the standards at points above andbelow and in front and in rear of the pivotal connection thereof.

It further consists in forming the pivot for the seat integral with thestop-plate and in a certain novel feature in the construction andarrangement of parts, all as hereinafter explained.

In the accompanying drawings, Figure 1 is a section elevation of a chairwith my improved device applied thereto; and Fig. 2 is a perspectiveView of the stop-plate, showing thehpivot for the seat formed integraltherewit The back legs and side arms of the chair may be constructed inany preferred way and have any desired ornamental configuration 5 butfor cheapness, lightness, and strength the same are constructed as shownin the accompanying drawings, in which the back standard A and front legA are made in one piece and the rear leg Bis made in one piece with thearm-support B, these parts being connected together in the form of an X,with the standard A, forming the back, extending up beyond thearm-support B and with the arm 0 extending from the top of the supportback to and connected with the standard. Cross-bars D extend between thestandards to form the back and head rests, and, if found desirable,cross-bars E may be connected to the front and rear legs.

A seat G, of any desired construction, has connected to each of its sidefaces a stopplate, which plate is provided with suitable perforations Nfor the passage of the bolts or screws for this purpose. The stop-plateconsists of the side bar H, with standards H projecting out from theside bar near each end and from the opposite edges thereof, and fromwhich standard project lugs or stops H the engaging faces of the stops Hbeing formed 011 an angle corresponding to the incline of the back andleg standard. Formed integral with the plate and projecting centrallyfrom the side face of the bar H and in the same direction as the stops His a cylindrical lug I, and which forms the pivot for the seat, beingadapted to engage perforations or bearings formed in the legs andarm-standards at the point at which they cross each other. Lugs or earsh near each end of the bar H project inward to engage the upper andlower edges of the seat, and which, in connection with the screws orbo1ts,serv,e to hold the plate in proper relation and firmly connectedwith the seat. Projecting from the rear edge of the backstandard andsecured thereto in any preferred manner are buffers h, with which thestops H on the plate engage.

From the foregoing it-will be seen that the stops in the plates engagethe back standards above the pivot of the seat and the legs at a pointbelow the same and that a very strong, light, and cheap construction ofchair is obtained and also one which, while being comfortable in use,maybe folded into very compact form.

Having now described my invention, I claim- Aseat having the backstandards and front legs made in one piece and the rear legs made in onepiece with the arm, in combination with a folding seat provided with astop-plate having the stops formed in an angle corresponding to theincline of the standards of the back and legs, substantially as setforth.

In testimony whereof I aflix my signature in the presence of twosubscribing witnesses.

DAVID A. SINSABAUGH.
